SGM8558-1/SGM8558-2/SGM8558-3/SGM8558-4

15MHz, 8V/μs, High Output Drive,

High Precision, Low Noise Operational Amplifiers

GENERAL DESCRIPTION

FEATURES

The SGM8558-1 (single), SGM8558-2 (dual),

SGM8558-3 (single with shutdown), and SGM8558-4

(quad) are low noise, high precision CMOS operational

amplifiers that provide a high output current of 230mA,

rail-to-rail output operation from a range of 2.8V to 5.5V

single supply. The SGM8558-3 is available with

shutdown pins that drive the output voltage low.

• Output Drive Capability: 230mA

• Low Input Offset Voltage: 15μV (MAX)

• Low Noise: 8nV/ Hz at 1kHz

√

• Unity-Gain Stable for Capacitive Loads to 780pF

• Gain-Bandwidth Product: 15MHz

• High Slew Rate: 8V/μs

• Open-Loop Voltage Gain (R_L= 2kΩ): 139dB

• Power Supply Rejection Ratio: 130dB

• Current Limitation: 230mA

The SGM8558-1/2/3/4 offer low input offset voltage, low

input offset voltage drift and high output current drive.

These devices also can achieve a high 15MHz

gain-bandwidth product and a high 8V/μs slew rate.

• Over-Temperature Protection

• No Phase Reversal for Overdriven Inputs

• Supply Voltage Range: 2.8V to 5.5V

• Supply Current:

The SGM8558-1/2/3/4 are specifically designed to

drive high current load, such as 32Ω headset, V_BIASof

RF power amplifier, etc.

0.86mA/Amplifier (TYP)

0.2μA (TYP) Shutdown Current for SGM8558-3

• -40℃ to +125℃ Operating Temperature Range

• Small Packaging:

The SGM8558-1 is available in Green SOIC-8 and

SOT-23-5 packages. The SGM8558-2 is available in

Green TDFN-3×3-8L and SOIC-8 packages. The

SGM8558-3 is available in a Green SOT-23-6 package.

The SGM8558-4 is available in a Green SOIC-14

package. They operate over an ambient temperature

range of -40℃ to +125℃.
